SUMMARYA study of London schoolchildren found that lung growth and function improved after the city introduced its ultra-low emission zone and restricted the most polluting vehicles. Researchers said the policy helped reverse pollution-related stunting of lung capacity seen in children living in the most affected areas. The findings link cleaner traffic policies with better respiratory development and long-term health benefits.

Children's lungs grew bigger and stronger after the most polluting vehicles were restricted from entering London, a study has found. Examinations of London schoolchildren before and after the introduction of the city's ultra-low emission zone found a restoration of lung capacity that had been stunted by exposure to pollution... "Traffic pollution in cities damages children's health and development," said Chris Griffiths, a professor of primary care at the University of Oxford and Queen Mary University of London, and the study's joint senior author. "We provide the strongest evidence yet on how these harms can be prevented. Ambitious clean-air zones should be considered a priority for cities globally with traffic-related air pollution."
Air pollution from traffic has stunted the development of children's lungs in London for decades. Previous research found that by the age of eight or nine, children from the most polluted areas had 5-10% less lung capacity than their peers elsewhere. That impairment, which scientists said was the result of exposure to nitrogen dioxide, put them at increased risk as adults of developing respiratory diseases, such as asthma and chronic obstructive pulmonary disease, cardiovascular and metabolic disease, and premature death.
